When using the NEW "Manage All Inventory" page to create a shipment to send to Amazon for FBA, we get an error. Here is what happens: after selecting the desired items and clicking on SEND/REPLENISH INVENTORY, I get a white screen with the following error "413 ERROR. THE REQUEST COULD NOT BE SATISFIED". It does not let me proceed any further. Please help.
What happens when you use the Send To Amazon workflow?
